The actor recently filmed his final scenes as John, whose story is expected to reach a dramatic climax in next week's post-watershed episodes of the soap.
John has been involved in three deaths in the last year and is currently holding brother-in-law Chesney Brown captive in a cellar alongside the parents of Charlotte Hoyle, who was one of his victims.
However, speaking on Loose Women this afternoon, Hawley commented: "I think the reason why the story has worked is that at the centre of it you have this incredibly boring, normal character that in any other situation, you just wouldn't even look twice at him. But then you put him into the most extraordinary situations that you can possibly imagine. For me, that's drama."
"That's always been the thing with me, to try and resist the temptation to kind of go cloak and dagger with it," he continued. "Because apart from anything else, that's been done and been done brilliantly - especially on Coronation Street. Brian Capron was brilliant [as] Richard Hillman, Tony Gordon as well. With all the soaps as well - these brilliant, deliciously bad villains."
Hawley went on to praise next week's Corrie episodes, which focus on a life-changing few days for the Stapes.
Discussing John's fate, he teased: "There is an ending - I couldn't possibly tell you what that ending is! There's two episodes tonight and at the end of tonight's second episode, it all blows up. And then we're on Sunday and all next week at 9pm.
"And it's a big week for Kate Kelly's character Becky as well. Really, it's the absolute meltdown of both those characters. It should be a brilliant week for Corrie so it's really worth watching."
